Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a ventilator mask. Background Art

[0002] There are two types of ventilator masks: nasal masks and oronasal masks.

[0003] A nasal mask, which covers only the patient's nose, is suitable for patients with mild to moderate sleep apnea. Its advantages are its relatively light weight, comfort, and exposure to the patient's mouth, making it convenient for oral tube insertion and suctioning. However, it is not suitable for patients with severe sleep apnea or those who require oral ventilation.

[0004] Oronasal masks cover a larger area, covering the patient's mouth and nose, and are suitable for patients with moderate to severe sleep apnea. They can provide higher pressure and a better seal, thereby improving treatment effectiveness. Although oronasal masks can also be used for patients with mild to moderate sleep apnea, they are less comfortable than nasal masks. In addition, air entering the stomach through the mouth may cause bloating, which can also affect the patient's appetite. Therefore, they should not be used unless necessary.

[0005] For these reasons, many patients experience severe symptoms upon admission and require an oronasal mask. However, as treatment progresses and their condition improves, they can stop using the mask and switch to a nasal mask for comfort, to prevent bloating, and to facilitate feeding and suctioning. This results in patients incurring the costs of both a face mask and a nasal mask. A ventilator mask that can switch between nasal and oronasal modes would be significantly more beneficial.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, the ventilator mask includes a nasal mask 1 and an oronasal mask component 2; the nasal mask 1 includes a nasal mask main body 11, a nasal mask lower body 12 and a connecting tube 13, the lower end of the nasal mask main body 11 is open, the nasal mask lower body 12 is detachably connected to the nasal mask main body 11 and closes the lower end of the nasal mask main body 11, and the connecting tube 13 is connected to the nasal mask main body 11; the oronasal mask component 2 can replace the nasal mask lower body 12 to close the lower end of the nasal mask main body 11. When the oronasal mask component 2 replaces the nasal mask lower body 12 to close the lower end of the nasal mask main body 11, the nasal mask main body 11, the connecting tube 13 and the oronasal mask component 2 form an oronasal mask 4.

[0024] The present invention can switch between the nose mask and the mouth and nose mask by disassembling the nose mask lower body 12 and the mouth and nose mask part 2. Figure 3 and Figure 4 As shown, the nasal mask body 11, the oronasal mask component 2 and the connecting tube 13 form an oronasal mask 4, which is suitable for patients with moderate to severe sleep apnea. The oronasal mask 4 can provide higher pressure and better sealing, thereby improving the treatment effect. Figure 1 and Figure 2 As shown, the nasal mask body 11, the nasal mask lower body 12 and the connecting tube 13 constitute the nasal mask 1, which is suitable for patients with mild to moderate sleep apnea, can improve comfort, and facilitate patients to eat and suction sputum, etc.

[0025] The utility model has a wider range of applications. In the early stage of hospitalization, the patient can switch to the oral and nasal mask 4; then, as the treatment progresses and the condition improves, the mask can be switched to the nasal mask 1. The utility model can adapt to various conditions of the patient and save costs.

[0026] The nasal mask 1 and the oronasal mask 4 are substantially the same in shape as the existing nasal mask and oronasal mask, respectively. The existing oronasal mask is substantially the same in shape as the existing nasal mask by only cutting off the upper part, which is also the theoretical basis for the design of the present invention. The specific structure of each component of the present invention can be partially referred to the existing technology, specifically as follows: the nasal mask body 11 includes a nasal mask arch 111, a nasal mask flexible pad 112 and a sealing strip 113. The upper edge, left edge and right edge of the nasal mask arch 111 are provided with a nasal mask flange 1111. The nasal mask flexible pad 112 is arranged along the nasal mask flange 1111 and is connected to the nasal mask flange 1111. The sealing strip 113 is arranged along the lower edge of the nasal mask arch 111. And it is connected to the lower edge of the arch part 111 of the nose mask; the lower body 12 of the nose mask includes a lower baffle 121 and a lower body flexible pad 122, the lower baffle 121 is fitted with the sealing strip 113, the edge of the lower baffle 121 has a lower baffle flange 1211, and the lower body flexible pad 122 is arranged along the lower baffle flange 1211 and connected to the lower baffle flange 1211; the lower baffle 121 is fitted with the sealing strip 113, and the lower body flexible pad 122 is fitted with the nose mask flexible pad 112.

[0027] The oronasal mask component 2 includes an oronasal mask arch portion 21 and an oronasal mask flexible pad 22. The lower edge, left edge and right edge of the oronasal mask arch portion 21 are provided with an oronasal mask flange 211. The oronasal mask flexible pad 22 is arranged along the oronasal mask flange 211 and is connected to the oronasal mask flange 211; when the oronasal mask component 2 replaces the nasal mask lower body 12 to close the lower end of the nasal mask main body 11, the upper edge of the oronasal mask arch portion 21 is fitted with the sealing strip 113, and the oronasal mask flexible pad 22 is fitted with the nasal mask flexible pad 112.

[0028] The nasal mask arch 111 and the oronasal mask arch 21 are used to cover the patient's nose and mouth, respectively. The nasal mask flexible cushion 112, the lower body flexible cushion 122, and the oronasal mask flexible cushion 22 are designed to conform to the patient's face. The connecting tube 13 is used to connect to the ventilator tube. The sealing strip 113 ensures a tight seal when the nasal mask body 11 is connected to the nasal mask lower body 12 or the oronasal mask component 2.

[0029] The specific method of connecting the nasal mask lower body 12 and the nasal mask main body 11 can be as follows: the nasal mask 1 includes a fastener 15, and a connecting seat 114 is provided on the nasal mask flange 1111 on the left and right sides of the nasal mask arch part 111; the fastener 15 passes through the nasal mask lower baffle 121 and is threadedly connected to the connecting seat 114, and the fastener 15 presses the nasal mask lower baffle 121.

[0030] The specific method of connecting the oronasal mask component 2 to the nasal mask body 11 can be as follows: connecting plates 24 are provided on the oronasal mask flanges 211 on the left and right sides of the oronasal mask arch portion 21; when the oronasal mask component 2 replaces the nasal mask lower body 12 to close the lower end of the nasal mask body 11, the fastener 15 passes through the connecting plate 24 and is threadedly connected to the connecting seat 114, and the fastener 15 presses the connecting plate 24.

[0031] The aforementioned method of connecting only with fasteners 15 does not connect the lower mask body 12 to the main mask body 11 on both sides, nor does it connect the oral and nasal mask component 2 to the middle of the main mask body 11. Furthermore, due to the obstruction of the connecting tube 13, it is also inconvenient to use the fasteners 15 there. Therefore, the present invention preferably adopts the following method: the connecting tube 13 is connected to the middle of the mask arch 111 and close to the lower edge of the mask arch 111; the mask 1 includes a socket 14, which is connected to the connecting tube 13 and has an elongated hole 141 arranged in the vertical direction; the lower mask body 12 includes a mask insertion rod 123, which is connected to the lower baffle 121 of the mask. The mask insertion rod 123 is inserted into the elongated hole 141 and abuts against the lower wall of the elongated hole 141. The oronasal mask component 2 includes an oronasal mask insertion rod 23, which is connected to the oronasal mask arch portion 21; when the oronasal mask component 2 replaces the nasal mask lower body 12 to close the lower end of the nasal mask main body 11, the oronasal mask insertion rod 23 is inserted into the long hole 141 and fits against the lower wall of the long hole 141.

[0032] The nose mask rod 123 is inserted into the slot 141 and abuts against the lower wall of the slot 141. The lower wall of the slot 141 restricts the downward movement of the nose mask rod 123, thereby restricting the separation of the nose mask lower body 12 from the nose mask main body 11. This prevents the nose mask lower body 12 from separating from the middle of the nose mask main body 11, thus ensuring a tight seal in the middle of the nose mask 1. For the same reason, the oronasal mask rod 23 is inserted into the slot 141 and abuts against the lower wall of the slot 141, thus ensuring a tight seal in the middle of the oronasal mask 4.

[0033] When connecting the lower mask body 12 to the main mask body 11, the lower mask body 12 is first tilted and the mask insertion rod 123 is inserted into the long hole 141 (because it is a long hole, the mask insertion rod 123 can be inserted even if it is tilted); then the lower mask body 12 is straightened and connected to the main mask body 11. The oronasal mask component 2 is connected to the main mask body 11 in the same way.

[0034] The ventilator mask requires straps 3, which are used to connect the ventilator mask to the patient's head. The straps 3 of the present invention are specifically configured as follows: the ventilator mask includes three straps 3, which are respectively connected to the nasal mask body 11, the nasal mask lower body 12, and the oral and nasal mask component 2. The straps 3 connected to the nasal mask body 11 include an annular belt 31 that wraps around the head and a top strap 32 that rests on top of the head when worn. The top strap 32 is used to prevent the mask from sliding downward.
